Force Vectors
Quick fact
Force vectors are used to describe forces like gravity, friction, and tension, all of which affect motion in specific directions.
Why this is interesting
Have you ever wondered why a ball rolls in a certain direction when you kick it? It’s not just about how hard you kick—it’s also about where you kick. That’s the power of force vectors.

Understanding Force Vectors
A force vector is a quantity that has both size (magnitude) and direction. Imagine pushing a box on a floor—how hard you push (magnitude) and the way you push (direction) together determine how the box moves.
A deeper explanation
When multiple forces act on an object, their effects can be combined using vector addition. This means we treat each force as an arrow pointing in its direction with length proportional to its strength. The resultant vector shows the overall effect of all forces. If the vectors balance out (sum to zero), the object is in equilibrium and doesn’t accelerate.
